Specification forming part of Letters Patent No. 218,964, dated August 26, 1879; application led June 19, 1879. A

To all whom imag concern:

Be it known that I, HARRY H. HEIsE, of Columbia, in the county of Lancaster and State of Pennsylvania, have invented a new and Improved Hydraulic Ram; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings,

forming part of this specification, in which- Figure 1 is a vertical section through line a: a: of Fig. 3. Fig. 2 is a vertical section through line y y of Fig. 3. Fig. 3 is a plan view With the air-chamber removed.

My invention relates to certain improvements in hydraulic rams, designed to render the same more simple, compact, and efficient.

The invention consists in casting the cylindrical base of the ramwith a face-plate for receiving the air-chamber, a central opening leading from the cylinder into the air-champlate, b, a `central hole, c, through the face' plate, and two discharge-conduits, d d, opening upon each side ofthe central orifice through the face-plate, and extending at right angles to the axis of the cylinder and across the periphery otl the same. Only one of i these discharge-conduits is necessary; 'but to permit the ram to be used in the various relations which may require the water to be elevated from either one side of the ram or the other I have formed the same with two opposite conduits, it being understood, however, that when any one of these discharge-conduits is being used the other is to be stopped up with a screw-plug, as shown in dotted lines.

B is the air-chamber, which is constructed with a plain surface and without any discharge pipe or conduit leading directly fromsaid chamber. It has, however, an open bottom, whose edges are faced to tit upon the face-plate of the subjacent cylinder, and are provided with lugs e e, which are clamped by bolts ff to lugs e e', formed upon the edges of the face-plate, so as to hold the air-chamber securely to the subjacent cylinder.

Between the air-chamber and face-plate is clamped a leather gasket, g, to which is hinged, upon one side, a flap-valve, h, covering the central hole leading from the cylinder into the air-chamber.

In constructing the valve 7L and gasket g, the leather of t-he gasket is cut in one and the same piece with the leather facing of said flapvalve. This causes the gasket to tightly close one of the conduit openings when the airchamber is clamped down, and maybe used independently of, or in connection with, a screw-plug .for stopping up one of said conduits.

Upon the end of the cylinder is formed a facing with lugs i i corresponding to the upper faceplate, and to which facingis clamped the cylinder-head C by means of bolts j, a leather gasket, 7c, being interposed to make a tight joint. This cylinder-head C also vforms a point of attachment for the bent spring l), which, at its lower end carries the waste-valve E, and 'at the same time forms a seat upon which said waste-valve plays and a wastedischarge through which the waste water ows.

In connecting the waste-valve to the bent spring a bar or casting, F, is bolted or riveted to the lower end of said spring, and is formed with a perforation through which a screwthreaded end of the valve E Iis extended, the stem of the valve being securely clamped at right angles to said bar by a shoulder, l, on said valve-stem and a nut, m. To regulate the extent of the play of the waste-valve an adjusting-screw, Gr, extends through a screwthreaded perforation on the end of bar F,

and when the valve is opened bears against the head of the cylinder.

In the operation of the ram, as thus described, the water enters through the inletpipe communicating with the open end of the cylinder, and the waste-valve is held open by the tension of the carrying-spring. Now, as soon as the escape of water around the valve and through the valve-seat acquires a certain momentum it closes the waste-valve, and with the acquired movement it then forces its Way 2 ISNM The cylinder'A, cast in one piece, with a face-plate, b, central hole c, and' one-or more transversely-extending discharge-conduits, d, in combination With an air-chamber having an open bottom and valves, substantially as described.
